GcmPubSub INVALID_PARAMETERS异常

Question

我在我的应用程序中实现了GCM.但是在一些版本之前它停止接收来自gcm的消息.当我通过http post发送消息时,谷歌说"InvalidRegistration".

调查显示,问题在于subscribeTopics(),它在最新版本中引发了INVALID_PARAMETERS.代码是

RegistrationIntentService.java

private void subscribeTopics(String token) throws IOException {
    for (String topic : TOPICS) {
        GcmPubSub pubSub = GcmPubSub.getInstance(RegApp.getContext());
        try {
            Log.i("KK_Reg", "Token to pubsub " + token);
            pubSub.subscribe(token, "/topics/" + topic, null);
            Log.i("KK_Reg", "PubSub subscribed");
        } catch (java.io.IOException ex) {
            Log.e("KK_Reg", "Subscribe topics error");
            Log.e("KK_Reg", ex.toString());
        }
    }
}

工作版和失败版之间的差异如下所示:

当然,我无法想象使代码失败的变化.请帮忙.
